Abstract
Description
Technical Field
[0001] The utility model relates to a carbon fiber tube rapid curing device, in particular to a carbon fiber tube rapid curing device, and belongs to the technical field of carbon fiber tube curing. Background Art
[0002] Carbon fiber refers to fibers with a carbon content of approximately 95% and graphite fibers with a carbon content of approximately 99%. Carbon fiber is made by firing fibers such as viscose, acrylic, aramid, and polyimide at high temperatures. Since the surface of carbon fiber tubes is very hot after production, they need to be cooled before further processing. Traditional cooling methods often involve spraying water on the carbon fiber tubes to achieve this cooling effect, which allows the carbon fiber tubes to solidify and form quickly.
[0003] The existing carbon fiber tube rapid curing device has a simple structure. The traditional method of cooling and curing carbon fiber tubes is mostly to directly cool the carbon fiber tubes with water. If the carbon fiber tubes are immediately cooled with water after being formed at high temperature, the water temperature is much lower than that of the carbon fiber tubes, which will cause the carbon fiber tubes to cool rapidly, thereby generating large thermal stress. This thermal stress may cause microcracks inside the carbon fiber tubes or even deformation, seriously affecting their shape, size and performance.
[0004] Therefore, there is an urgent need to improve a carbon fiber tube rapid curing device to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of the present utility model is to provide a carbon fiber tube rapid curing device, which changes the traditional method of using water to cool the carbon fiber tube body that has just been high-temperature formed by setting a slow cooling structure, so as to avoid the carbon fiber tube body generating large thermal stress due to rapid cooling due to the water temperature being much lower than that of the carbon fiber tube body. First, the raw materials for making the carbon fiber tube body are added to the interior of the screw extruder through a feeding hopper, and the screw extruder heats the raw materials and extrudes them from one end of the screw extruder. Then, one end of the extruded raw materials will be supported by an arc tray to prevent it from falling. Then, the electric guide rail is started to drive the transmission block to move toward the direction of the cooling box until the carbon fiber tube body enters the interior of the cooling box through the feed port. After entering the interior of the cooling box, the carbon fiber tube body will fall Place it on the placement rack, and then start the cooler to cool the carbon fiber tube body. The carbon fiber tube body can adjust the temperature suitable for cooling the carbon fiber tube body according to actual conditions. Finally, the cooled carbon fiber tube body is pushed out to the outside of the cooling box through the discharge port. In the process of pushing the carbon fiber tube body, the water-absorbing sponge will absorb the water droplets on the carbon fiber tube body due to cooling, so as to avoid the water droplets affecting the subsequent use of the carbon fiber tube body, and then the carbon fiber tube body is processed in the next step. The advantage of this structure is that the temperature for cooling the carbon fiber tube body can be adjusted to a suitable temperature, so as to better cool the carbon fiber tube body, avoid micro cracks or even deformation inside the carbon fiber tube due to large temperature difference, and prevent affecting its shape, size and performance.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0027] like Figure 1-Figure 7 As shown, this embodiment provides an embodiment of a carbon fiber tube rapid curing device.
[0028] A carbon fiber tube rapid curing device includes a screw extruder 1 and a carbon fiber tube body 2. A feeding hopper 3 is installed on the top of the screw extruder 1. A slow cooling structure 4 is provided on the screw extruder 1. The slow cooling structure 4 includes a cooling box 5 fixedly installed on one side of the screw extruder 1. A cooler 6 is fixedly installed on the cooling box 5. An electric guide rail 7 is fixedly installed below the carbon fiber tube body 2. A transmission block 8 is installed on the electric guide rail 7. A connecting rod 9 is fixedly installed on the top of the transmission block 8. An arc tray 10 is installed at one end of the connecting rod 9. A feeding port 11 and a discharging port 12 for use with the carbon fiber tube body 2 are respectively opened on both sides of the cooling box 5. A placement rack 13 is fixedly installed inside the cooling box 5, and a water-absorbing sponge 14 is fixedly installed on the inner side of the discharging port 12.
[0029] like Figure 4As shown, one end of the connecting rod 9 is provided with a plurality of mounting holes 15, and a spring 16 is fixedly installed inside the mounting hole 15, and a clamping block 17 is fixedly installed at one end of the spring 16. A socket 18 adapted to the connecting rod 9 is provided on the arc tray 10, and a plurality of clamping holes 19 for use with the clamping block 17 are provided inside the socket 18. Through the arrangement of the absorbent sponge 14, the mounting hole 15, the spring 16, the clamping block 17, the socket 18 and the clamping hole 19, the clamping block 17 can be engaged with the inside of the clamping hole 19 under the elastic action of the spring 16, so that the arc tray 10 can be fixed on the connecting rod 9 to prevent the arc tray 10 from falling off from the connecting rod 9. When the arc tray 10 is pulled, the clamping block 17 will be squeezed and shrink to the inside of the mounting hole 15. After the clamping block 17 is detached from the inside of the clamping hole 19, the arc tray 10 can be disassembled, which is convenient for disassembly and replacement when the arc tray 10 is damaged.
[0030] like Figure 4 As shown, one end of the block 17 is set to be arc-shaped. By setting one end of the block 17 to be arc-shaped, the friction force at one end of the block 17 can be reduced, so that the block 17 slides more smoothly inside the socket 18, thereby facilitating the installation and disassembly of the arc tray 10.
[0031] like Figure 5 As shown, a limiting groove 20 is provided on the feeding hopper 3, and a cover plate 21 is installed on the feeding hopper 3. A limiting plate 22 adapted to the limiting groove 20 is fixedly installed on the bottom of the cover plate 21. Through the arrangement of the limiting groove 20, the cover plate 21 and the limiting plate 22, the cover plate 21 can close the feeding hopper 3 when the screw extruder 1 is not in use, so as to prevent dust or debris from being introduced into the screw extruder 1 through the feeding hopper 3. After the limiting plate 22 is engaged in the limiting groove 20, the stability of the cover plate 21 can be improved to prevent the cover plate 21 from falling off.

Through the setting of the first fixed plate 23, the first electric telescopic rod 24, the fixed block 25 and the cutter 26, the first electric telescopic rod 24 is started to extend and drive the cutter 26 to descend, so that the cooled carbon fiber tube body 2 can be cut to a length suitable for use in different scenarios, saving personnel time for subsequent cutting.

Through the arrangement of the connecting hole 27, the rod 28 and the bolt 29, the rod 28 is inserted into the inside of the connecting hole 27, and then the rod 28 is rotated to adjust the angle of the bolt 29 to be perpendicular to the angle of the connecting hole 27, so that the cutter 26 can be fixed on the fixed block 25 to prevent it from falling off. When the rod 28 is rotated to adjust the angle of the bolt 29 to be consistent with the connecting hole 27, the rod 28 can be pulled out, thereby facilitating the disassembly and replacement of the cutter 26 when it is damaged.

By setting the second fixing plate 30, the second electric telescopic rod 31 and the clamping plate 32, the plurality of second electric telescopic rods 31 are started to extend and drive the clamping plates 32 to move closer to each other, so as to clamp and fix the extended carbon fiber tube body 2, thereby preventing the cutter 26 from shaking when cutting the carbon fiber tube body 2, which may affect the cutting accuracy.
[0035] In this embodiment, if Figure 1-Figure 7 As shown, the working process of the carbon fiber tube rapid curing device provided in this embodiment is as follows:
[0036] First, the raw materials for making the carbon fiber tube body 2 are added to the interior of the screw extruder 1 through the feeding hopper 3. The screw extruder 1 heats the raw materials and extrude them from one end of the screw extruder 1. Then, one end of the extruded raw materials will be supported by the arc tray 10 to prevent it from falling. Then, the electric guide rail 7 is started to drive the transmission block 8 to move toward the cooling box 5 until the carbon fiber tube body 2 enters the interior of the cooling box 5 through the feed port 11. After the carbon fiber tube body 2 enters the interior of the cooling box 5, it will fall onto the placement rack 13. Then, the cooler 6 is started to cool the carbon fiber tube body 2. The carbon fiber tube body 2 can be adjusted according to actual conditions to be suitable for cooling the carbon fiber tube body 2. temperature, and finally the cooled carbon fiber tube body 2 will be pushed out to the outside of the cooling box 5 through the discharge port 12. In the process of pushing the carbon fiber tube body 2, the water-absorbing sponge 14 will absorb the water droplets generated on the carbon fiber tube body 2 due to cooling, so as to avoid the water droplets affecting the subsequent use of the carbon fiber tube body 2, and then the carbon fiber tube body 2 will be processed in the next step. The advantage of this structure is that the temperature of cooling the carbon fiber tube body 2 can be adjusted to a suitable temperature, so as to better cool the carbon fiber tube body 2, avoid micro cracks or even deformation inside the carbon fiber tube due to large temperature difference, and prevent affecting its shape, size and performance.
[0037] In summary, in this embodiment, according to a carbon fiber tube rapid curing device of this embodiment, through the arrangement of the water-absorbing sponge 14, the mounting hole 15, the spring 16, the clamping block 17, the jack 18 and the clamping hole 19, the clamping block 17 can be engaged with the inside of the clamping hole 19 under the elastic action of the spring 16, so that the arc tray 10 can be fixed on the connecting rod 9 to prevent the arc tray 10 from falling off from the connecting rod 9. When the arc tray 10 is pulled, the clamping block 17 will be squeezed and shrink to the inside of the mounting hole 15. After the clamping block 17 is detached from the inside of the clamping hole 19, the arc tray 10 can be disassembled. Therefore, it is convenient to disassemble and replace the curved tray 10 when it is damaged. By setting one end of the block 17 to be arc-shaped, the friction force at one end of the block 17 can be reduced, so that the block 17 can slide more smoothly inside the socket 18, thereby facilitating the installation and removal of the curved tray 10. By setting the limiting groove 20, the cover plate 21 and the limiting plate 22, the cover plate 21 can close the feeding hopper 3 when the screw extruder 1 is not in use, so as to prevent dust or debris from being introduced into the screw extruder 1 through the feeding hopper 3. After the limiting plate 22 is engaged in the limiting groove 20, the stability of the cover plate 21 can be improved. To prevent the cover plate 21 from falling off, the first fixing plate 23, the first electric telescopic rod 24, the fixing block 25 and the cutter 26 are set, and the first electric telescopic rod 24 is started to extend to drive the cutter 26 to descend, so that the carbon fiber tube body 2 after cooling can be cut, and the length suitable for use in different scenarios can be cut, saving the time of subsequent cutting by personnel. Through the setting of the connecting hole 27, the insertion rod 28 and the bolt 29, the insertion rod 28 is inserted into the inside of the connecting hole 27, and then the insertion rod 28 is rotated so that the angle of the bolt 29 is adjusted to be perpendicular to the angle of the connecting hole 27, and the carbon fiber tube body 2 can be cut. The cutter 26 is fixed on the fixing block 25 to prevent it from falling off. When the insertion rod 28 is rotated so that the angle of the latch 29 is adjusted to be consistent with the connecting hole 27, the insertion rod 28 can be pulled out, so as to facilitate the disassembly and replacement of the early cutter 26 when it is damaged. By setting the second fixing plate 30, the second electric telescopic rod 31 and the clamping plate 32, the multiple second electric telescopic rods 31 are started to extend and drive the clamping plates 32 to move closer to each other, so as to clamp and fix the extended carbon fiber tube body 2, thereby preventing the carbon fiber tube body 2 from shaking when the cutter 26 cuts the carbon fiber tube body 2, which may affect the cutting accuracy.
